The Conch Shell

Use the following writing prompt to inspire you to write a scene:

You and your significant other go to the beach. While walking along the beach, you find a conch shell and hold it to your ear. Instead of hearing the sounds of the sea, you hear a voice whispering instructions to you. You place the shell by your partner’s ear, but he hears only the sound of the wind and the waves. What is the voice telling you? And what do you do about it?
